Abstrakty
We present the notion of bounded second κ-variation for real functions defined on an interval [a,b]. We introduce the class κBV2([a,b]) of all functions of bounded second κ-variation on [a,b]. We show several properties of this class and present a sufficient condition under which a composition operator acts between these spaces.
